Fix a crash provoked by x `op` y = x op = True The trouble was that there is currently a single 'infix' flag for the whole group; and RnTypes.checkPrecMatch was therefore expecting the second eqn to have two args. This fixes the crash, and also or-s the infix flags for the various eqns together; previously it was just taken from the first eqn, which was wrong.
